Injection Process Overview

Injection Demo

Manufacturing Engineering Workflow

A precise 5-step process ensures a void-free hermetic seal within the 0.1 mm annular gap.

01Plasma Activation

02Vacuum Degassing

03L-Type Dispensing

04Stepped Curing

05ISO Integrity Test

Structural Integrity & Safety Margins

Validation based on First-Principles of solid mechanics and ASTM standards.

Safety Redundancy (FOS)	~3,846x against 5 psi
Theoretical Burst Limit	19,047 psi
Thermal Endurance	Stable up to 450°F / Tg 155°C
Filling Dynamics	Washburn Imbibition: 2.8s to 28s

Strategic Mechanism Analysis

Feasibility evaluation of sealing modalities relative to the 1 mm spatial limit and 0.1 mm eccentricity.

Mechanism	Core Physics	Suitability
Laser Welding	Metallic lattice fusion	Low (Gap Sensitive)
Elastomeric (O-Ring)	Elastic recovery	Critical (Height limit)
Mechanical Swaging	Hertzian stress	Critical (Collapse risk)
Polymer Bonding	Capillary dynamics	Optimal

Sealing Material: Master Bond EP42HT-2Med

The injection process utilizes EP42HT-2Med, a medical-grade epoxy known for high-temperature resistance and superior biocompatibility.

Mix Ratio (A to B)	100:40 (Weight)
Working Life (100g)	45 - 75 minutes @ 75°F
Tensile Lap Shear	> 2,000 psi (Al to Al)
Sterilization Protocol	100+ Cycles (Autoclave, EtO, Gamma)
